S6, E21: To give Darrin more ambition, Endora puts a spell on him giving him the push and verve that he needs. He takes it a bit too far when he takes control over an account and he and Larry was working on together. Darrin then has no time for Samantha or the children because of this spell and Samantha gets through to him by telling him that he is under a spell and to undo the damage he caused.
